Add-on BIOS

3.1.4

Extended System BIOS Area (E_0000h-E_FFFFh)

This 64 KB area (000E_0000h – 000E_FFFFh) is divided into four 16 KB segments.

Each segment can be assigned independent read and write attributes so it can be

mapped either to main DRAM or to DMI Interface. Typically, this area is used for RAM

or ROM. Memory segments that are disabled are not remapped elsewhere.

Non-snooped accesses from PCI Express or DMI to this region are always sent to

DRAM.

BIOS Extension

3.1.5

System BIOS Area (F_0000h – F_FFFFh)

This area is a single 64 KB segment (000F_0000h – 000F_FFFFh). This segment can

be assigned read and write attributes. It is by default (after reset) Read/Write

disabled and cycles are forwarded to DMI Interface. By manipulating the Read/Write

attributes, the GMCH can “shadow” BIOS into the main DRAM. When disabled, this

segment is not remapped.

Non-snooped accesses from PCI Express or DMI to this region are always sent to

DRAM.
